I can live with doubt, and uncertainty, and not knowing. I think it’s much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I’m not absolutely sure of anything, and in many things I don’t know anything about, such as whether it means anything to ask why we’re here, and what the question might mean. I might think about a little, but if I can’t figure it out, then I go to something else. But I don’t have to know an answer. I don’t feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesn’t frighten me.

The differentiations of sex, age, and occupation are not essential to our character, but mere costumes which we wear for a time on the stage of the world. The image of man within is not to be confounded with the garments. We think of ourselves as Americans, children of the twentieth century, Occidentals, civilized Christians. We are virtuous or sinful. Yet such designations do not tell what it is to be man, they denote only the accidents of geography, birth-date, and income. What is the core of us? What is the basic character of our being?
